 * Usage:
 *  $(selector).sparkline(values, options)
 *
 * If values is undefined or set to 'html' then the data values are read from the specified tag:
 *   <p>Sparkline: <span class="sparkline">1,4,6,6,8,5,3,5</span></p>
 *   $('.sparkline').sparkline();
 * There must be no spaces in the enclosed data set
 *
 * Otherwise values must be an array of numbers or null values
 *    <p>Sparkline: <span id="sparkline1">This text replaced if the browser is compatible</span></p>
 *    $('#sparkline1').sparkline([1,4,6,6,8,5,3,5])
 *    $('#sparkline2').sparkline([1,4,6,null,null,5,3,5])
 *
 * Values can also be specified in an HTML comment, or as a values attribute:
 *    <p>Sparkline: <span class="sparkline"><!--1,4,6,6,8,5,3,5 --></span></p>
 *    <p>Sparkline: <span class="sparkline" values="1,4,6,6,8,5,3,5"></span></p>
 *    $('.sparkline').sparkline();
 *
 * For line charts, x values can also be specified:
 *   <p>Sparkline: <span class="sparkline">1:1,2.7:4,3.4:6,5:6,6:8,8.7:5,9:3,10:5</span></p>
 *    $('#sparkline1').sparkline([ [1,1], [2.7,4], [3.4,6], [5,6], [6,8], [8.7,5], [9,3], [10,5] ])
 *
 * By default, options should be passed in as teh second argument to the sparkline function:
 *   $('.sparkline').sparkline([1,2,3,4], {type: 'bar'})
 *
 * Options can also be set by passing them on the tag itself.  This feature is disabled by default though
 * as there's a slight performance overhead:
 *   $('.sparkline').sparkline([1,2,3,4], {enableTagOptions: true})
 *   <p>Sparkline: <span class="sparkline" sparkType="bar" sparkBarColor="red">loading</span></p>
 * Prefix all options supplied as tag attribute with "spark" (configurable by setting tagOptionPrefix)
 *
 * Supported options:
 *   lineColor - Color of the line used for the chart
 *   fillColor - Color used to fill in the chart - Set to '' or false for a transparent chart

 *   chartRangeMinX - Specify the minimum value to use for the X range of the chart - Defaults to the minimum value supplied
 *   chartRangeMaxX - Specify the maximum value to use for the X range of the chart - Defaults to the maximum value supplied
 *   composite - If true then don't erase any existing chart attached to the tag, but draw

 *           existing chart is detected.

 *   disableHighlight - If set to true then highlighting of selected chart elements on mouseover will be disabled

 *   tooltipFormatter  - Optional callback that allows you to override the HTML displayed in the tooltip
 *       callback is given arguments of (sparkline, options, fields)
 *   tooltipChartTitle - If specified then the tooltip uses the string specified by this setting as a title
 *   tooltipFormat - A format string or SPFormat object  (or an array thereof for multiple entries)
 *       to control the format of the tooltip
 *   tooltipPrefix - A string to prepend to each field displayed in a tooltip
 *   tooltipSuffix - A string to append to each field displayed in a tooltip
 *   tooltipSkipNull - If true then null values will not have a tooltip displayed (defaults to true)

 *       (eg. to map -1 to "Lost", 0 to "Draw", and 1 to "Win")
 *   numberFormatter - Optional callback for formatting numbers in tooltips
 *   numberDigitGroupSep - Character to use for group separator in numbers "1,234" - Defaults to ","
 *   numberDecimalMark - Character to use for the decimal point when formatting numbers - Defaults to "."
 *   numberDigitGroupCount - Number of digits between group separator - Defaults to 3
